For Those That Have Used The Suprelorin Implant

[OSoSwift]

No he still worked just as well and had the same food drive as normal, it was just at meal time. I also found it a little harder to get as much as he needed into him while training for the ET. I had to feed him twice daily instead of the normal once daily then a chew of some sort in the morning.

His temperment didn't appear to change. He did mark less but was still trying to mate my bitch when she was in season.

Slowing down of metabolism, by the sounds.

SecretKei .... you know you have to allow about 6 weeks (I'm going from memory, I think that's right) for the implant to have become as effective as it might be?

[OSoSwift]

I was told four weeks and I would have to say I think that was about right. Rommi came into season at around 3 and a half weeks after the implant and although he was interested he was no where near as interested as prior to the implant ( until she was standing then he would have happily obliged, but was the same 10 months down the track)

His testicles shrunk fairly quickly as well and maybe shrunk until 6 weeks??

Oh and he certainly wasn't any lazier - much the same as normal which is pretty active for a Whippet.

OOS, did you find that the implant lowered the dogs food drive overall? Or he just ate slower/less at actual mealtimes?

I'm considering one for my Ridgie as I'll be bringing home a female shortly (who will be kept entire).

I was planning to go with a 6 month implant to see how it affects him, then to make a decision re desex, vasectomy or continue with the implant. However with the possibility of lowered food drive and a lazier dog I'm dabbling with the idea of a vasectomy instead...

It didn't with my Kelpie. I think this is another individual dog effect as my boy is still a hoover!

I have just redone my boy. It appeared to last about 15mths for him- testes where starting to get bigger and he was showing more interest in the ladies but that was the only noticeable difference. There was no change in muscling or temperament- he is a mummies boy regardless lol.

Thank you for the answers. I was planning on using the 6 month implant initially. Given that it takes around a month to be fully effective I was planning on having my boy done when my female pup reaches 5-6 months (presuming that she would have her first season around the 7-10 month mark).

It is really just to get us through that first season safely. From there I will make the decision on whether to re-implant. Well that is the plan anyway...

[OSoSwift]

I wish I had of gone the 6 month one initally

[Red Fox]

Why is that OOS?

[OSoSwift]

Because I am still freaking about it lasting for 2 years as I want to mate him around January/February. Because I used the 12 month one his fertitlity may not return in time ( assuming he is not one of the 1% who never get it back ) If I ahd of used the 6 month one that then lasted for 9 to 12 months we would be right.

[OSoSwift]

I know I am stressing about something I have no control over and shouldn't be stressing over, but as his testicles have got only marginally bigger I am worried..............

[but my bitch is on it now - 1 year dose - and she's a porker! Well, a porker from her skinny days.... ;)

--------------------------------------

Are you using this for your bitch for the same thing - ie not to be fertile for 6 or 12 months? Or is it for incontinence? Would be very interested in hearing info/details of how the bitch went on it, and the effects of it, if it was for stopping her coming into season please.

Yep! It was preferable ( at the time) to getting her spayed and it was worked really well - the 1 Year implant lasted for about 2 years and she's only just come back into season now. I've re-implanted a 1 Year dose and she seems fine. Having had a chat with my vet though it seems Suprelorin works 50-50 in bitches - and it's a lucky thing it's work in my bitch. Apart from the weight gain, it's been awesome! No side effects, no season, no nothing!

Good luck!

Okay my latest update.

Lewis's implants's 12 months was up at the start of August.

Now I thought that his fertility should return fairly quickly after that date (unless he was going to be one of the ones that didn't would be just my luck!!!) Anyway I was chatting with our vet about it who told me that after the implant has worn off there will be a period of around 60 days before the testosterone is at a level high enough to produce sperm, then another 60 days before that sperm is available and present in ejaculate. So essentially the 12 month implant will last a minimum of 16 months.

So I emailed the company and this is the reply I got

If you dog has started to show behaviours that were present prior to implantation (marking and scenting), in addition to a slight increase in testes size, it is highly likely that testosterone production has resumed and therefore sperm production would have also resumed. As per your veterinarians statements there is a lag phase from when testosterone has returned to when viable sperm is produced. There needs to be sustained levels of testosterone for a period of 8-9 weeks for viable sperm. In your dogs case as he has just started to show signs of fertility, I would wait another 2 months and at this time he should be fertile.

Suprelorin (4.7mg) and Suprelorin12 (9.4mg) last for a minimum of 6 and 12 month respectively. The actual length of suppression time will depend on the individual dogs sensitively to the active drug (deslorelin). The return to fertility rates are stated below:

Suprelorin Summary: 80% within 12 months

98% within 18 months

Suprelorin12 Summary: 70% within 2 years

95% within 2.5 years

Now I may just be very blonde but to me if something is labelled as 12 months I would assume that they should be back to normal fairly close to that time. I have never been told at anytime that it will take a minimum of 16 months, and yes I read up their page and didn't see these figures. I googled and found some info from the European market which stated theese figures, hence why I emailed them.

Now in my case I had to use this for a medical reason, but had I known this I would have only used the 6 month on as with the return to fertility times the 6 month one would have easily covered the time I was wanting to cover, where as the 12 month one last 16 months may be too long - we will see I guess.

Anyway, at this point Lewis does have slightly larger testicles and is marking more and is not putting up with Rommi trying to push hima round so I am confident he has started producing testosterone I just hope he has viable sperm within the time we need it.

Basically the 6 month implant will last at least 9 to 10 months, and the 12 month one will last at least 15 to 16months, when it comes to return to fertility - not necessarily testosterone production and behaviours associated with that. So something to keep in mind.

Thanks for the info Oso. I had to give my boy the implant for medical reasons. Originally was going for the 6 mth implant then when it came to it, the specialist pretty much told me me, hes decided on the 12 mth and I went with it, because with everything going on, my head was all over the place and I hadnt had time to actually sit and think it out. Im regretting the 12 mth implant, especially now after reading your update. Its been 3 months now since the implant, his testes have shrunk but not as small as I was expecting. Do you think they are likely to get smaller as time goes on, or should that be it now? My boys behaviour has changed. He IS lazier, he is not as happy, excitable and out there like he used to be, which I really miss and he is also not as confident as he used to be. He is very well socialised but now some things he reacts to that he never would have prior to implant. He is not "nervy" just not %100 percent confident like he used to be. I have read that castration/implant can have an affect on dogs like that.

Im also concerned that he was given the implant at 14 mths old, no where near mature. Obviously its going to have an affect on him maturing fully whilst the implant is in. Do you think once it wears off he will start to mature again, once producing testosterone again?

I have heard of larger dogs having the implant wear off sooner than the 12 mths, I can only hope that will be the case with my boy, then again my next worry will be whether the "problem" that required the implant in the first place has settled down. I just cant wait to have my "old" dog back. I still love him like he is I just miss the old him.

[OSoSwift]

Kaffy I am feeling the same.

I did want to use my boy at stud and the 12 month implant I thought would be okay for the time frame, now luckily my bitch had a longer cycle, but even then it will be close. Had I known I would have used the 6 month one and would have been covered for what needed to be and had plenty of time for it to wear off properly.

You can get it surgically removed if required.

I really thought Lewis hadn't changed much but he is eating better - as he was pre-implant - and his attitude to training is much much better and much more drivey and much more resiliant and he has stood up to Rommi on a couple of occassions, where as he didn't when he had the implant. He has also "thickened" up for want of a better term. His muscle seems harder and whilst not bulky he seems thicker, but not fatter.

In a way I am thankful it is available as it would have meant desexing one permanently otherwise, but I still wish I had of gone the 6 month one-especially after getting that info.

Within 3 months Lewis's testicles were around a third their size but didn't shrink after that time so I would think his will probably stay that size now.

I hope my "diary" is helpful as I didn't really find much info about peoples experiences when I was looking. I know every dog is different and responds differently but I hope this may help someone

Thanks for the update - I have been keeping an eye on this thread. I thought about Hamish having the implant, I doubt he will be used at stud but want to keep my options open.

I spoke with someone a few months ago who had his dog done only to find that it wore off around 10 months later when his bitch was gaining weight. Took her to the vet and sure enough - she was pregnant.

How typical - dog being fertile when you don't want it and delayed when you do.

Think I will leave Hamish as he is for now, at least while he is easy to manage.

Hope his fertility returns soon.

Well wouldn't that annoy the crap out of you!!!!!

I actually prefer his temperment etc when he isn't on it so unless he has a medical issue he will be left entire. We will ahve to see if the condition he had before returns and then decide what to do if it does. I won't be using it again unless absolutely necessary!

We are collecting him in around 7 to 10 days (when our teaser is standing) so will let you know the results. From what the company says it will be too early but I have someone else wishing to use him at stud so want to make sure what is going on. If it was my own I would mate them and see what happened!!!

Anymore updates on this Oso? Did you get him collected?

[OSoSwift]

Anymore updates on this Oso? Did you get him collected?

NO I didn't end up getting him collected :)

Due to the time line, the fact his testicles were still small and the bitch I had tee'd up was actually going out not coming in it didn't happen.

I also spoke to the owner of the bitch who was looking at using him and we decided that the chances of him being fertile for her were extremely slim so she ended up flying her to her breeder and got her mated and flown home. She had 8 lovely puppies.

His testicles while marginally larger are still not back to normal size, so I am assuming his fertility will still be compromised. One good thing though is he does seems to have all his normal testosterone linked behaviours coming back - not that he had heaps to begin with, but hey, I'll take what I can. I am not expecting it to return before around 22 months after it was first implanted due to what I have read about others experiences with it. I am hoping his fertility does return by two years, if not I will be very very peeved!

My bitch is due to come into season any time and I will mate them. As it is my own bitch I will probably not worry about collecting him first, but will see when the time is closer, if she goes another 3 months as she may, then he may have normal sized testicles and then I wouldn't bother. But if they are still the size they are now then I may as if his sperm is very low I don't really want to risk producing a singleton and then having the complications that can come with that if I don't need to.

I really wish I had of got the 6 month one................

I have found this thread to be of so much interest & information, thank you all very much. I have decided not to use it on my young male but would be interested to learn more about using it in incontinent females. I had to have my whippet bitch neutered at 12 months because she got a pyo after her first season. She's been intermittently incontinent ever since. I use stibestrol (? spelling) which helps most of the time but not always. An implant would be better if it works 100% of the time. Has a anyone used it successfully? My girl is rising 8 years of age.

[OSoSwift]

I know of one person who has used it I think on two Lab bitches and I think from memory it isn't a 100% cure but used with low doses of Propalin works quite well. I will PM you the persons name as I think you may know of her :)
